Blues halfback Piri Weepu has recovered from heart surgery and is expected to be available for selection for the Anzac Day Super Rugby clash with the Waratahs.

Weepu's improved health game as the Blues announced a much-improved medical report across the squad as they enjoyed a bye in the latest round of the demanding championship.

Keven Mealamu, Patrick Tuipulotu, Peter Saili, Kane Barrett, Tom Donnelly, Jamison Gibson-Park and Jackson Willison will all return to full training this week and provided they come through unscathed will be available for selection against the Hurricanes for Friday night's match in Wellington.

Weepu could take the field the following week which would be a relief for all concerned after the All Black was diagnosed with heart problems late last month.

He suffered a minor stroke back in early March and played three games subsequent to that problem.

A scan revealed a small hole in his heart and he had surgery last week to address that.

The Blues medics said the 71-test veteran had made a full recovery with no residual deficits from the earlier stroke and was also back trianing.

The 30-year-old Weepu last played in the March 22 win over the Cheetahs at Eden Park.

They lost badly to the Brumbies in Canberra the next week without him.

With their week of inactivity through the bye, the Blues have slipped to bottom of the tight New Zealand conference and 11th overall in the 15-team championship.
